Abstract : This study was conducted to determine the physiological index and stress of washing chickens in the cement plant area of LAFARGE (Ewekoro) and Dangote (Ibese) in Ogun State. 100 adult eaten chickens consisting of 25 chickens from LAFARGE, Dangote and their respective neighboring communities (Imasaya and Wasimi) were used. Experimental birds were captured from roosts during the night and caged until the next morning. Data on rectal temperature, pulse and respiratory rate of the birds were collected. 5 ml of blood was also drawn via the chicken wing vein at each site using a sterilized needle and syringe and transported to the laboratory for analysis. Significantly (P<0.05) the highest heart rates (215.64 beats per minute) and respiratory rates (19.90 beats per minute) were recorded in LAFARGE (Ewekoro) range samples and the lowest (198.61 beats per minute and 16 .00 beats per minute).or 93 breaths/minute) in Imasaya. There was no significant difference (P > 0.05) in the rectal temperatures of the birds in the study area. Significant differences (P<0.05) were also found in hematocrit (PCV), hemoglobin (Hb), white blood cell count (WBC), monocytes and glucose levels in zone Dangote chickens. Study with the highest (P<0.05) .05) Thehematocrit (28.06%) and hemoglobin (4.01 g/dL) were recorded in Ibese, and the minimum hematocrit (22.00%) and hemoglobin (288 g/dL) in Imasaya. The maximum (P<0.05) Monocytes (4.28%) and glucose (256.53 g/dl) were detected in scavengers in Dangote (Ibese), while the lowest number of monocytes (0.00%) and glucose (194.53 g/dl) was found in chickens in Wasimi. The maximum (P<0>0.05) Difference in the ratios of heterophils, lymphocytes, basophils and heterophils/lymphocytes in the chickens of the study area. The study showed that chickens reared in LAFARGE (Ewekoro) were stressed and had health and welfare status compared to Dangote Cement Area (Ibese) and other farming communities. An effective environmental mitigation program should be implemented to improve the welfare of feed chickens at the LAFARGE cement factory.
